摘　　要：为了实现有源消声,提出基于凸组合滤波器的凸组合算法。首先设计凸组合算法步长更新律,使新权值更新收敛系数与输出功率成反比,从而得到凸组合算法,实现噪声的消除。最后利用Matlab中Simulink工具箱中的数字信号处理工具包进行仿真,验证了所提出方法的有效性。In order to solve the problem of active noise control system, a convex algorithm based on convex filters is proposed. This paper proposes the convex algorithm by convex filters and applies the double filters with the designed the update law by the output power of the system to solve active noise control problem. The proposed algorithm has a better performance by a simulation.
